As shown in FIG. 1, a shoulder keyboard 1 includes a keyboard body 2 having a substantially rectangular shape as a whole, a triangular neck portion 3 formed so as to extend from one end in the length direction of the keyboard body 2, and a keyboard body. 2 and the neck portion 3 are connected to each other by an oblique connecting portion 3a. Note that the connecting portion 3a may be omitted. The keyboard body 2 is composed of a keyboard portion 5 on the front side as seen from the player, which is arranged side by side on the mouth stick portion 4, and a panel portion 6 on the front side.

The neck portion 3 is provided with a bender device 7 for temporarily raising and lowering the pitch of the played performance sound to change the performance expression. 2 and 3 are an external perspective view and a longitudinal sectional view of the bender device 7, respectively. As shown in these figures, the bender device 7 includes a variable resistor 8 rotatably mounted inside the neck portion 3, an operation lever 9 for rotating the variable resistor 8, and a variable resistor 8. It has a return spring 10 for returning from the rotating position to the original position.

The variable resistor 8 constitutes a bender circuit together with a circuit (not shown), and changes the resistance value due to the rotation of the variable resistor 8, which temporarily raises or lowers the pitch of the performance tone after being generated. The variable resistor 8 is composed of a resistor main body 11 and a rotary shaft 12 integrated with the resistor main body 11. At the rotary shaft 12 part, a support plate 13 screwed in the neck part 5 is provided with a vertical direction of the neck part 3. It is attached so as to rotate about the axis of the above, that is, the axis A orthogonal to the surface of the neck portion 3.

The operation lever 9 is a plate-shaped lever main body 14 arranged on the back side of the surface material of the neck portion 3 and along the same, and the operation lever 9 projects from the lever main body 14 to the surface of the neck portion 3 to extend the length of the neck portion 3. The operating portion 15 extends linearly in the vertical direction. The lever body 14 has a resistance holding portion 16 at its tip (right end in FIG. 2), and the rotary shaft 12 of the variable resistor 8 is fitted and held in a holding hole 17 formed in the resistance holding portion 16. . The operation portion 15 projects slightly upward from the opening 18 formed in the surface of the neck portion 3. The opening 18 has a fan-shaped planar shape, and the center of the fan-shaped opening is formed so as to coincide with the rotation fulcrum of the variable resistor 8. Further, a guide groove 19 is formed on the back side of the surface material of the neck portion 3 along the outer peripheral edge of the fan-shaped opening 18, and engages the rotation side end portion (the left end portion in FIG. 2) of the lever body 14. Then, the rotation is guided.

The return spring 10 is composed of a torsion coil spring, and the coil portion 10a is wound around the resistance holding portion 16 of the operating lever 9, and both leg portions 10b and 10b (only one is shown) are rearward (see FIG. 2). It extends to the middle left) and is fixed to the support plate 13, and a protrusion 20 provided on the lower surface of the lever main body 14 engages between the both leg portions 10b and 10b to move the operation lever 9 to the neutral position. It is supposed to be restored.

Further, on the panel section 6 of the keyboard body 2, a tone color selection button 21 for selecting a tone color output from the tone generator section and a mode selection button 22 for selecting a tone color output mode are provided on the keyboard. A large number are provided side by side along the length direction of the main body 2. The timbre selection button 21 is composed of ten number buttons, each of which is numbered 0 to 9, and the performer pushes the number button to select a timbre number. The tone generator outputs the tone of the tone color corresponding to the tone number, as in the case of 01, the tone of the organ.

The mode selection button 22 is composed of, for example, two push buttons. When both buttons are not pressed, a single tone color output mode selected by the tone color selection button 21 is set, and one button is pressed. When you press, the output mode allows you to select one tone from the tone groups that the performer has selected and set in advance.When you press the other button, regardless of the performer's selection. It is configured to be in an output mode in which one tone color can be appropriately selected from among the tone color groups preset on the keyboard.

The mouth stick part 4 is provided with a display part 23 for displaying the selection states of the tone color selection button 21 and the mode selection button 22. The display unit 23 is configured, for example, by arranging three LEDs of 7 segments side by side, and the LED on the left side when viewed from the player shows the selection of the output mode by the mode selection button 22 in the alphabet. The two LEDs are used to display the tone color selection state by the tone color selection button 21 by number.

Next, a performance operation of the shoulder keyboard 1 having the above-described configuration will be described. As shown in FIG. 1, the shoulder keyboard 1 is hung from the shoulder using a shoulder strap 24, and the keyboard part 4 is played with the right hand, and the bender device 7 with the left hand and the tone selection buttons 21 with the left or right hand. And the performance is performed by appropriately operating the mode selection button 22. In this case, since the display unit 23 is provided on the mouth stick unit 4, the player can directly see the display on the display unit 23 in the normal playing posture during the performance, and the both selection buttons 21, The 22 selected states, that is, the tones being produced and the output modes thereof can be easily confirmed without breaking the playing posture.

When the operation lever 9 is not operated, the operation portion 15 of the operation lever 9 of the bender device 7 is operated by the return spring 10 engaged with the protrusion 20 of the operation lever 9, As shown in FIG. 2, the variable resistor 8 positioned at a position substantially parallel to the length direction of the neck portion 3 and connected to the operation lever 9 is held in a neutral position that does not raise or lower the pitch of the performance tone. .

When operating the bender device 7, as shown in FIG. 4, first, as in the case of playing a guitar, the neck portion 3 is supported between the thumb of the left hand and the base of the index finger, and the index finger is inserted. The fingertips of the finger and the middle finger are applied to the operation portion 15 of the operation lever 9. When raising the pitch of the playing sound, the fingertips of the forefinger and the middle finger of the left hand are abutted against the operating portion 15, and the operating lever 9 is pushed up against the spring force of the return spring 10, for example, upward in FIG. As a result, the operating lever 9 rotates together with the variable resistor 8 integrated therewith about the axis A in the vertical direction, and the resistance value of the variable resistor 8 decreases, for example, so that the pitch of the performance tone is changed. It can be raised in proportion to the turning angle of 9.

In addition, the operation opposite to the above, that is, the fingertips of the forefinger and the middle finger of the left hand are hooked on the operation portion 15 of the operation lever 9 and pulled down to increase the resistance value of the variable resistor 8, The pitch of the performance sound can be lowered according to the turning angle of the operating lever 9.
